DETROIT May 15 (Reuters) - General Motors Co is
recalling 140,067 Chevrolet Malibu sedans in the United States
for a potential faulty braking issue, according to documents
filed with U.S. safety regulators.

GM is recalling certain mid-sized cars from the 2014 model
year equipped with a 2.5 liter gasoline engine with the
automatic stop/start option because the hydraulic boost assist
could become disabled, according to documents posted online on
Thursday by the National Highway Traffic Safety Administration.

Slowing or stopping the vehicle could require additional
brake pedal effort and a lengthened stopping distance,
increasing the risk of a crash, according to the filing.

GM is in the midst of recalling 2.6 million cars to replace
defective ignition switches linked to at least 13 deaths.

GM officials were not immediately available to comment.

GM said in the NHTSA documents that the brake issue was
discovered during development testing for an upcoming model on
April 24, and after further testing an order for dealers to stop
selling the cars was issued May 7.

Dealers will update the electronic brake control module
software, according to the filing. The recall is expected to
begin around May 30.

In a separate filing, GM is also recalling 477 Chevy
Silverado and GMC Sierra pickup trucks and Chevy Tahoe SUVs in
the United States because an improperly tightened tie rod may
result in the loss of steering and increase the risk of a crash.
The 2014 model year is affected for pickups trucks and the 2015
model year for SUVs.

Dealers will inspect the tie rods to ensure they are
properly tightened and replace steering gear as necessary,
according to the filing. The recall began on Wednesday.
